e2fsck

[Francesco Pietra <frapietra@alice.it>]

A quick question related to

"in general it is not safe to run e2fsck on mounted filesys-
       tems.  The only exception is if the -n option is specified, and -c, -l,
       or  -L  options  are not specified.   However, even if it is safe to do
       so, the results printed by e2fsck are not valid if  the  filesystem  is
       mounted.    If e2fsck asks whether or not you should check a filesystem
       which is mounted, the only correct answer is ‘‘no’’.  Only experts  who
       really know what they are doing should consider answering this question
       in any other way"

How to check the filesystem (ext3) if it is not mounted?

That because I got warning that max count nr reached, suggesting to run 
e2fsck.

Thank you
